Application Research Of Genetic Algorithm And Case Based Reasoning For Numerical Control Machine Tool Design

Complex mechanical product design is the key research content of the whole design phase.Is also the domestic and foreign scholars have been concerned about the problem.How to design a fast and efficient design of the product,which plays a key role in the enterprise market.This paper studies complex mechanical product design issues from the perspective of intelligent.Case study with CNC lathes complex mechanical product design,the genetic algorithms and case-based reasoning applications.Firstly,the principle and application of genetic algorithm are introduced.Application of genetic algorithm to design of multi-level complex product design the use of multi-level algorithm,modular design structure optimization.CNC lathe design and modular structure of the program through a combination of SQL server 2008 in the VC ++ 6.0design platform.In view of the structural characteristics of the CNC lathe,a detailed design of the module is designed by using the case based reasoning.Using the extension theory to construct an example database.Using the gray correlation algorithm for Euclidean case base based search.According to the actual situation to modify the instance to meet the design requirements.Finally,the modified instance is stored.The main index of the design scheme is evaluated by using fuzzy comprehensive evaluation method based on analytic hierarchy process.Fuzzy comprehensive evaluation method can realize the evaluation of the module and the overall scheme of the score,so that the design of the scheme can be modified.In order to meet the needs of customers,we can modify the design of the scheme.So as to realize the design of the scheme design,and then redesign.
